I don’t have anyone I know locally who can help. I’m sitting watching the tech and service guy talk through the windows and am not feeling confident.
I the meantime you can search Inet for car audio shops in your area and make some calls asking if they can do a harness repair if you provide the right connectors. If they say they can, send them the pics and ask them if they still can and how much. Looks like there are a few north of you in Pasadena.
 
understandable and sometimes sometimes thats the answer but this is an easy repair. id ask for a price on just a harness repair
I got to take a look at the damage and it god further up the harness. My insurance company is now involved since this was caused by a fire which is clearly covered.

In looking carefully at the photos and learning that the damage is further up the wires, I think it’s more likely this is rodent damage and the chewing on insulation caused a short that led to the melting and further damage. Look for rodent nesting material in your cabin filter (after putting the HVAC system in RECIRC). They got in somehow I think.
 
^^^^^ This above is what I've witnessed first hand as well - rodents can cause an incredible amount of damage. If you happen to not catch it early, it's likely to grenade something super small that ends up being enormously expensive.

Funny you guys should say that, I found a dead mouse on the engine cover a month ago.
 
Believe it or not, soldering is not the best way to repair this. The cost of it isn’t the only reason there is no solder in our factory harness, a proper crimp is better for strain relief and avoiding problems in the future. The operative word here is “proper” crimp.. that’s easier said than done.

I totally believe there is other damage further up, and that really does complicate any repair to this example. Insurance is probably a good move.

Got the quote of $8225 for the job, insurance is involved now. I’m hoping that this is covered under our policy. What’s messed up is our bumper to bumper warranty just expired a couple of months ago.
 
The bumper-to-bumper warranty may not have covered it if indeed is rodent caused.
Hopefully insurance will cover it either fire or rodent.

I assume that price includes a new harness and that Toyota does in fact still make the part?
 
If you end up deciding to repair the harness and the insurance/warranty/dealer doesn't work out give No Limit Baltimore a call. Their electrical tech can maybe even make you a harness . At least we discussed making harnesses when I was upgrading the alternator on my LC.
 
We had a similar issue with our 2016 LS460…the air conditioner would only blow max cold and some other stuff was happening. It also ended up being the whole dash wiring harness.

The car was gone for 3 months, but my local indy Lexus shop was able to do it, and my aftermarket warranty covered the whole repair (it was roughly ~$10k).

Feel free to PM me if there’s any info you need that could help you. It is a huge repair so make sure whoever does it really knows what they’re doing. Here’s a photo of the dash harness for my LS.

Is that plug available?

If so, that doesnt look like all that hard of a repair, just splicing in new wires in place of the melted ones.

I have done this on various rigs, in place, in the vehicle.

If plug isnt available separate, can still be somewhat easily repaired using a Deutsch connector with the same wire count.

This isnt as bad as you think

If it were me, i would be looking for a donor harness to pillage the OEM plugs from and then just splice in the repair:

Something like this:

I am waiting to hear back on whether our insurance covers this. If they don't, then I will be going this direction and taking the vehicle somewhere else on a flat bed.
 
FYI, you can bypass the plug completely. You may need to splice in wire to maintain length but you can splice out the existing connectors. I am guessing that if you were to find the appropriate connectors you will still need to replace all of the pins anyway so splicing around the connectors is cost effective and I’m not sure if those connectors ever come into use after assembly but I’ve never unplugged one.
 
Hope it works out for your insurance!!

If not, my guess is when you tell the Dealership your taking it somewhere else, they will try to make you a "deal" on the repair, rather than lose the $$ - then they'll sub it out for splicing into a OEM plug

Just heard back from our insurance appraiser and adjuster, it's totally covered under the comprehensive policy. Dealership is ordering the parts they need to get her back on the road soon. Total cost with parts and labor came out to $8225.

Nice.

I guess this is the one exception to my PSA about always locking the glove box and keeping the key blade with you when you leave your rig at the dealer..

But check your recirc flap. Seriously.
